T LZZ whom. it nuty concern,.-

Be it known that I, JOHN H. GooDFnLLow, acitizen ofthe United States, residing in Lowell, in the county of Middlesex, State of Massachusetts, have invented certain new and useful Improvements in Machines for Carding Safety-Pins, duc., of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

ro The object of this invention is to provide a machine for attaching safety-pins to cards or strips of paper in a rapid and satisfactory manner, the hand-carding of such pins, which has been practiced hitherto on account of the t5 peculiar character of the articles to be handled, being necessarily slow and expensive. The machine in which the invention is embodied and has been illustrated in the accompanying drawings for purposes of explanazo tion comprises means for separating the pins from a collected mass or bulk, means for sorting them, so that they shall be presented properly. to the devices which follow, means for taking them from the sorting devices and presenting them to the card or paper,means for preparing and presenting the card or paper, and various other parts which are more or less incidental to certain of the lnechanical devices above referred to. It is to 3o be understood, however, that not all of these various mechanical devices are of necessity associated in one machine and that the invention is not to be restricted to their application together to a single struct-ure nor to 3 5 the precise construction and arrangement of the various devices which are herein shown and described.

In the drawings, Figure lis a front side elevation of a machine which embodies the 4o several features of the invention. Fig. 2 is a plan View of the same, parts below the work-table being indicated by dotted lines. Fig. 3 is an end elevation of the machine seen from the left of Figs. l and 2. Fig. Llis a transverse section on the plane indicated by the dottedline 4L 4 of Fig. 2. Figs. 5, 6,

7, and 8 are detail views of parts to be referred to hereinafter.

The work table or bed of the machine upon or with relation to which most of the Working parts are supported is represented at A,

being mounted upon a suitable frame A. A driving-shaft Bis supported in suitable bearings beneath the table and is provided with a driving-pulley C and a loose pulley C. Various cams and eccentrics are fixed upon the shaft B and are arranged to cause various mechanical devices to perform their allotted functions at predetermined intervals of time, as more fully described hereinafter. 6o

A hopper or reservoir D is supported at a suitable elevation above the work-table to receive the safety-pins in mass or bulk. Its bottom is inclined or slotted, and in the slots are mounted blades d, which are pivoted at the rear, while their forward ends are united and through a suitable finger d' rest upon a projection d2 from a vertically-reciprocating blade d3. The latter is wholly in front ofthe reservoir or hopper D, and its upper edge d4 7o is inclined at the same angle as the bottom of the hopper, withwhich it is substantially flush when the blade is in its lowest position. The blade cl3 is reciprocated by any suitable means, such as the link d5, lever d, and cam or eccentric D on the shaft B. The blades d do not fall below the bottom of the hopper, but at each upward movementof the blade cl3 the finger d is struck' by the projection d2, so that the mass of pins in the hopper is 8o shaken up, causing the pins to slide forward one after another on the extended bottom of the hopper, suitable stops being provided to prevent the pins from sliding beyond the vertically-reciprocating blade d3. As the side walls which bound the extension of the-hopper-bottom converge, as clearly shown in Fig. 2', the pins are guided over the reciprocating blade (Z3, by which they are lifted, straddling its upper edge, as clearly shown in Fig. 8.

A notched feed-wheel E is supported upon a suitable standard in line with the verticallyreciprocating blade cl3 and in close proximity thereto, being driven by any suitable means, as by a cord e and pulleys e c2, from the driving-shaft B. Each notch c3 of the WheelE is of such a depth as to receive from the inclined upper edge d4 of the reciprocating blade d3 only one safety-pin, the safety-pin sliding down the said inclined edge against loo the feed-wheel. As the feed-wheel rotates the safety-pins are carried over, as clearly shown in Fig. 8, and are deposited upon the sorting-blade F, which is inclined, so as to permit the pins to slide downward upon it, and being at first substantially vertical and straddling the feed-wheel, as atf, is gradually flattened out, with the farther edge depressed somewhat, so that all of those safety-pins which pass onto the flattened portion f with the pin-points uppermost, as shown in Figs. '7 and 8, will slip off into a suitable receptacle F', while the remaining pins will slide down toward the lower end of the sorting-blade. From the lower end of thesorting-blade the pins are permitted to passone at a time to the devices which present them to the card or paper. A trip mechanism is provided for the purpose of releasing the pins one by one, such trip mechanism comprising an arm G, which is pivoted upon the side of a vertical standard and is forked at its upper end, one partg underlying the sorting-plate F and having spurs g', which project upwardly through openingsin said plate, while the other part g2 overlies said plate F. As the arm or bar Gr is rocked upon its pivot the spurs g are withdrawn from the plate F, permitting one pin which before was lodged against them to slide down against the upper part or arm g2, which lies farther forward, and by the same movement is brought against the upper side of the plate, thus stopping the pin which has been released by the spurs. As the arm or bar rocks backward the spurs rise through the plate F to detain the next pin, while the upper arm g2 releases that held b y it and permits it to slide farther down the plate F. The arm or bar G is conveniently operated by a lever g3, which is pivoted upon the work-table A and is drawn in one direction by a spring g4, while its short arm g5 bears against or at the proper time makes contact with another lever, hereinafter to be referred to. The pins slide from the end of the sorting-plate F through a suitable guide-chute F2 into the grasp of the conveying or transferring device. This lastnamed device comprises two gripper-jaws H, which are mounted to slide in a suitable guideway affixed to the table A, the said jaws being pivoted together upon a pin 7L and being provided at their forward ends with studs h to enter the eye of the pin, as clearly shown in Fig. 4. The jaws are normally pressed apart by a spring h2 and are caused to reciprocate together in the guideway provided therefor by any suitable means, such as av forked lever h3, (which also operates the triparm G, above referred to, through the lever 93,) a connecting-rod h4, and a cam or eccentric H' on the shaft B. In order that the jaws vH may close and open at the proper time,

they are made to slide forward between two operating-jaws H2, which are pivoted upon the work-table and form the forward part of the guideway. The rear ends of these operating-jaws H2 are formed with cam-faces h5 to cause the jaws H to close upon the pin as soon as they commence their forward movement, and the forward or free ends of said operating-jaws are engaged by levers h6, operated by cams H3 on the shaft B. The cams H3 are so placed that they cause the operatingjaws H2 to open, thereby releasing the gripper-jaws H and permitting them to release the pin which has been held by them at the moment when the gripper-jaws have reached the limit of their forward stroke. The point of the safety-pin is caused to enter the card or paper during the forward movement of the gripper-jaws, and after it has been inserted in the card or paper it is desirable to close the pin, causing its guard to engage the point. For this purpose an anvil-block I, having a narrow slot 7l in its upper face, is mounted just below the path of movement of the pinpoint and is caused to rise after the pin-point has passed above it by any suitable means, such as a lever vl and a cam or eccentric I on the shaft B. With the anvil coperates a presser K, which operates upon the upper or guard member of the pin, pressing it down to cause the guard to engage the pin-point after the Ylatter has penetrated through the card or paper. As represented, the presser consists of a lever suitably notched, as at 7s, to engage the pin and operated at the proper time by any suitable means, as a connectingrod 7c and a cam or eccentric K on the shaft B.

So far as concerns the operation of the devices already described, the card or paper to which the pins are to be affixed may be fed, prepared, and supported by hand or by any suitable mechanism; but the machine shown in the drawings is represented as provided with mechanical devices for handling a continuous strip of paper. As represented in the drawings, the paper is supplied from a roll L, which is mounted in suitable standards and is provided with a suitable brake Z. From the roll it passes through a crimper or folder Z', which gives to the strip of paper the form necessary to permit it to be engaged readily by the pin-points. The crimper or former consists of a suitably-shaped metallic shell and base, which are cut away to permit the feed-rolls Z2 Z3 to engage the paper strip and are also cut away in line with the anvil I to permit the pin to be inserted, the shell being extended farther to form a convenient guide for the strip and to permit the cutter, hereinafter referred to, to operate properly. The converging sides of the shell, which is open below, turn the margins of the strip down, so that the strip at the point where the pins are inserted is in sectionan inverted U. The lower feed-roll Z2 may be mounted in fixed bearings. The upper feed-roll is preferably mounted in arms Z4, which are pivoted upon the table and are provided with set-screws Z5, whereby the pressure of the upper roll may be regulated. The roll Z3 is provided with a ratchet-wheel Z5, which is fixed to the shaft of the roll, the said ratchet-wheel being engaged bya pawl Z7, carried by an arm Z8, which is also mounted, but loosely, on the shaft ofA IOO IIO

the feed-roll. It is desirable that the strip should be fed forward more rapidly at certain times than at others in order to leave suit' able spaces at intervals where the strip can be cut to form shorter lengths, and mechanism has been devised and will presently be described whereby this result can be accomplished. The arm Z8, above referred to, is connected to one end of a rod or bar M, which is supported to slide longitudinally and is provided with a projection m. Parallel with the rod or bar M is a short fixed shaft fm', upon which is mounted a sleeve m2, having fixed thereon a 'ratchet or crown wheel m3. A pawl m is mounted on the frame to engage said ratchet and cause the forward movement thereof in a rotary direction as the ratchet is brought in contact therewith through its longitudinal reciprocatory movement on its axis, which is eected through the medium of a bell-crank lever m5, a connecting-rod m6, and a cam or eccentric M on the shaft B. The rear edge of the ratchet-wheel is adapted to engage the projection m on the rod or bar M in its movement to the rear, whereby a short movement of the bar is effected. The rear edge of the ratchet-wheel is also provided with one or more studs mi, disposed at regular intervals, so that when one of these studs is brought into line with the projection m. and the ratchet-wheel is moved to the rear, or to the left in Fig. l, the movement of the rod or bar M is commenced earlier and has a greater extent. The shorter movement of the bar causes a sufficient movement of the feed-roll to advance the paper strip sufficiently to receive the next pin in succession, while thelonger movement of the bar in the same manner causes the stri p to be fed forward a much longer distance, leaving a space for the convenient counting of the pinsor where the strip can be cut.

The cutter-blade N is suitably mounted at the end of the work-table and is held normally in its elevated position by a spring n. It is drawn down to cut the strip at the proper time by a lever n', operated by a cam N/ on the shaft B. In order that the cutter may be operated at the proper intervals, the cam N is secured to a sleeve n2, which is free to slide longitudinally on the shaft B, but is compelled to rotate therewith, and the cam itself normally stands out of line with the lever n'. The end of the sleeve is formed with a camnose n3 to coperate with a corresponding cam n, which surrounds the shaft B, but is iixed to the framework. The sleeve is grooved and engaged by a lever n.5, the end of which stands in the path of movement of the rod or bat` M, so that it is struck thereby as said bar approaches the limit of its longer movement, thereby causing the cutter to be operated at the proper time to sever the strip in the space between successive groups of pins. As soon as the cam N has completed the movement of the cutter the fixed cam n4, acting upon the rotating cam-nose n3, will lforce the cam N' out of line with the cutter-lever n' and through the lever a5 will push the rod or bar M back, if that is necessary, although the spring mx, which restores the rod or bar after its shorter movement, may also restore it after the longer movement. e

In the operationA of the machine described the pins in mass are placed in the hopper D and the roll of paperis placed in its bearings and the end of the strip led forward through the former and between the feed-rolls. The machine being then set in motion, the pins are separated, sorted, delivered to the gripper-jaws, and inserted in the paper strip over the anvil, the pin beingclosed after it has been inserted in the strip. The strip is stationary while the pin is being inserted, but is fed forward step by step as the gripperjawsretire and at certain intervals is fed forward a longer distance. The operations of the several parts have been described in detail hercinhefore and need not be explainedv again. n
